Light-based “LiFi” is stunningly fast, notably fragile—and now standardized
GarlicBender, All wifi is light-based…
xavier666, Need c/angryupvote for this
INeedMana, 
Beam? What happened to the fibre? Is light that slower in a fibre cable?
aurelian, 
I wonder if this iteration will end up being the iteration that finally becomes viable.
BrikoX, 
Estonia has been testing it since 2015, but their projected timeline for adoption never realized.
themeatbridge, Sorry, but how is this faster than wifi?
BartyDeCanter, Theoretical max for Wi-Fi in the 60GHz spectrum in 7G/s. Theoretical max for Li-Fi is 228G/s. Of course, no one is hitting those maxes now but in general Li-Fi is about 10x faster in the real world, or at least is you have the right prototype equipment.
Physics reason- LiFi uses shorter wavelengths so can switch faster.
themeatbridge, Thank you, that makes sense. So the downside is you need line of sight and no interfering light sources?
BartyDeCanter, Pretty much. I wouldn’t worry too much about interference from other light sources, as they are likely to be basically steady and not modulating.
rockerface, 
so if we get to GammaFi we can be even faster
django, And penetrate walls much better.
